they look the business-

but i was really after something alittle bit more versatile-and compact as i will be using them alot and they just look too damn bulky!!-if im going up a flight of stairs-im buggered-

i do alot of shows for around 600-1000 people in banqueting suites and big halls. so need the power of twin loaded cabs but they gota be compact and easy to move-such as the ev's and cerwin's (1 man job) , if any1 can get hold of the planz for the ev Mtl's or cerwin Sub218-thatz would be very much appreciated!!

Why not use 2 1850 horns a side[ easier to carry up stairs] and don't forget each 1850 horn uses 1x 18 inch.

As dual 18 inch horn subs are very large and extremely heavy.

Or if you still want to build dual 18 inch horn sub, heres the plans:[it won't be able to go up flights of stairs though].

 

http://mitglied.lycos.de/crusher844/ - http://mitglied.lycos.de/crusher844/

Find Plaene and click it on there, and it's the 2x 18" DB-B2.

 

Dat is the B2. Fundamental bass. This is not Konstruirter plan like many different, but a 1:1 to the Orginal. The B2 is built and driven out by the company D&b. It is a band-pass filter 6er order (no BP/HORN) the front expanding haven serves only for the pressure adjustment to air. The depth of the loudspeaker is with seitenbrettern 58cm. each interior chamber has approx. 125L. The 3te chamber in the center itself the two 18"er parts has 100L. Alternatiev can be equipped the B2 also with B&C PZB 46. But the rear haven must be 25,5cm long in each case. The RCF L18P300 gets along something similar well with the tuning. The efficiency is constant 102dB 1w1m, the B2 comes however clearly deep and pressure-full as the Mutator. For the enormous pressure the Relatiev large one radiating surface is responsible. The middle haven both chassis divide is approximately 41,5cm long and is forward extended

nah not too keen on that design mate, i had 2x 1850 earlier this year i put a fane 18xb driver in there and --woo hoo i saw sum fireworks

so im not too keen on them, as they killed my beloved fane 18xb's  or was it the crown 3600vz at full whack for 5 hours 

im still looking for that double 18'' design, i like the ''pimp'' styling of the ev and cerwins u just see the big f**k off baskets and magnets! and the whole cab is same size as a scoop, but housing 2 18''s

@Insomnia

listen man those selenium double 18s that NEXUS-3 mentioned are awesome there aint nothing like them

ive never heard a better double 18 in my life, i must highly recomend them they do a lot of damage and the bass is 10 out of 10!           trouser flappers at 30 yards

i was over a mile away on a beach when some guy was using 8 double 18s not only could i feel the bass in my chest i could feel it in the floor

......just all them hanging there like giant bananas.

The other thing is, I'm sure you can split that Selenium cab up into two units - one driver in each - to make transportation alot easier. Stacking two together should give alomst identical output.

anyone got any pics of the finished Selenium cab?

Try to PM Marjan M he is using Selenium bass cabinets but with 15' Eminence Kappa pro 15 LF.The cabinet for a 18'  drivers  is  few inches biger.

Especially if they're true horns designed to do 50hz or lower and not a bandpass hybrid.

Quote nah not too keen on that design mate, i had 2x 1850 earlier this year i put a fane 18xb driver in there and --woo hoo i saw sum fireworks

Then you shoulda put the right driver in it or used the 186 box instead, thats user error, not the box's fault.

Also the boxes you're talking about (if i'm thinking of the right ones) are not truly horns but micro-scoops or bandpass/manifold hybrids

yes,

the cabs im after are some sort of micro-scoops,  

ive used the Ev Mtl's before - they are effecient enough throughout the hole spectrum but just lack any major power as they are rated at around 800-per cab,

I may try the selenium design after ding some research into it.

No, you can get some doubles just abit bigger than scoops-but just cost too damn..and not very good value for money when u consider each cab is  800rms

How about this dual BP6 box *ahem*, about as small as they come and 1200wrms

They sound good, i've just modelled the PD186 in the box compared to the Beyma LX60 thats in them, heres the plot, the green is the PD with 1200w input power

The Beyma obviouslly has a smoother frequency range then.


Posted By: LunchieTey
Date Posted: 17 September 2005 at 5:30am
...I'm sure it's just that one has imported FR data(green line) and the purple(beyma) is just a theoretical plot with no FR data given and just plotted from T/S specs(or dif programs and the graph is transposed)....

Ever seen a bass bin with a perfectly flat line response graph? Obviosly it's just a plot,not REAL response!

If the PD is in the green, then I HIGHLY doubt that the beyma has THAT smooth of responce and must be a model.

They're both models, for some reason the majority of drivers have a lumpy response in the box, but a couple (like the Beyma) are completely smooth

I saw these plans a couple of years ago, but didn't try them out. Any people in UK using these with PD186/Fane XB/B&C ?

Anyone modded this design? I would prefer a box 4ft high (approx 122 cm), so mids and tops are nice and high, would be using ply, so weight and size not such an issue for me, if I am mostly using just 2 per side.

This looks really good, not sure about the drivers though, what about using the Void 600w 18"? would keep the cost down, and still be a 1200w cab.

the beyma lx60 range are nails, got 4 of the 12's in a pair of dual bp/horn hybrid subs, makes me wanna hear a lab sub for comparrison

 

would be good fun to knock off a copy of danleys b-deap and bung a pair of them in, i can see why he reakons there is no longer a huge need for 15 & 18 inch drivers. 

if you are set on dual 18's i'd at least try modelling the beyma lx's anyway

OK, so anyone here willing to give a quote to build a pair of these beasties ? (wire'd, wheel'd, trimite'd, handle'd and dual speakon'd, of course)..


Posted By: DJ Dave

the angles get goofy. they cost me 300.00 us to make plus the drivers 190 each x 4. they are really strong.

I see you're selling them seperate from the drivers.  Why?

I will sell the drivers for 180 each.

I was going to use them for the next project, What ever that may be.

I reckon you would be looking at well over £500 for a pair, not including drivers, built out of birch ply to a professional finish.

   Hi angus, need help with the selenium cab designs.  you've said that it can be split into two in order to have one 18's in a single cab.
   What would be the effect if the width will be increased? from the original plans the width is 100 cm, if split in two, 50 cm or 19.6 inches. What would be the effect concerning the quality of sound if i will increase the width to let say 23.6 inches or 60cm while the rest of the measurements remains the same.
   thanks for your help.

Hi Xmax extreme,

I have not read the forum in detail for some time now (a couple of months maybe) so I have only just seen your post. Sorry about that.

If you want good performance from this, and you want to split it up into two boxes, then you need to split the box exactly into two.

The internal width of each box would be 960 / 2 = 480mm and all other internal measurements would be the same.

If you increase the (external) width to 600mm, the internal width would be:

600 - (2*20) = 560mm

This is 80mm bigger than the plans. This would have the effect of increasing the volume of the box by:

80 / 480 * 100 = 16.66%

The volume in the plan is given as 42 litres, so this would increase to 56 litres I reckon. I can't comment on what exact effect this will have on the sound of the finsihed cabinet but I reckon if you want the best results use the specced driver and build the cabinet as close to the plans as possible.

Cheers,
Angus

   Hi Angus,
 
   Wow, thanks for that very clear explainations, now i have the a better understanding with the plans and by using the exact driver.  
   Before I have the idea to increase the width when spilt in to two since I have compared it to the 186 plan which has a wider width. And as you have mentioned from the original plans, it has only 42 liters volume, so i pressumed  that increasing the volume would give me a lower frequency cut-off and I could use another driver.
  
   Well, thanks again angus.
 
 
   Best regards,

Hi! I am planning to build this enclosure for my small disco mobile here in the Philippines, I have some questions to clarify.
 
1. I dont have access to high quality speaker, I only have P Audio, can I use P Audio as replacement for Selenium speaker?
2. Do I need to build 2 or more per side to achieve its performance or one per side is enough?
3.What would be the cut-off frequency for my Active cross-over using this HB1805C1 enclosure?
 
Hoping to hear you very soon.
Thank you very much,
 
Very sincerely,
Bosbacs

*small* mobile disco ..... ummm, these are huge mate, and require big tops and big amps, and make some serious bass! (ie: 1000people+ crowd)

if your volume mad build a G-Sub, that'll cover your needs easily and be easier to find drivers for.

Increasing width will
Increase front chamber volume(good,lowers cutoff slightly)
Increase rear chamber volume(not good,if its too big,excursion increases below cutoff.)
Increase the horn area along its entire length will result in even the horn near throat being wrong.
Cutoff wont be lower because the length is the same.
 
It would probably well enough though.
